    Abstract: Due to the deviations caused by testers’ understanding and executing of GB 3906—2006, IEC 62271-200:2011 etc standards, there are many problems arising in actual operation and test of medium voltage AC metal-enclosed switchgear. This paper researched on the relevant standards at home and abroad, and made a thorough analysis of the difficulties in the insulation test of medium voltage AC metalenclosed switchgear, such as humidity correction, examination of internal and external insulation, lightning impulse test procedure and criterion, examination of observation windows and shutter, longitudinal insulation test of switch, and pointed out the problems needed to pay attention in the actual test, which provides references for the technicists working on high-voltage test detection.
    Key words: insulation test; humidity correction; longitudinal insulation; internal insulation; shutter
